Abstract :
We report impurity-free selective disordering by RTA with thick and thin SiO/sub 2/ caps for an InGaAs/AlGaAs strained QW structure. We present Fabry-Perot (FP) lasers integrated with selectively-disordered passive waveguides and demonstrate reduction of the passive waveguide loss. In the experiment, an InGaAs/AlGaAs strained single QW graded-index separate confinement heterostructure was used.
